- * ----------	-------		------------------------------------------------

- * 	Date			version	  	Description

- * ----------	-------  	------------------------------------------------

- * 01/25/2007	1.1			Bug is Fixed in the Indirect Mode 

- *							: Memory mapping error	

- * ----------	-------		------------------------------------------------

- * 01/08/2008	1.2			Modification of Socket Command Part

- *							: Check if the appropriately performed after writing Sn_CR

- *

- *							Modification of SPI Part

- *							: SPI code changed by adding 'spi.h'.

- *							: Change control type for SPI port from byte to bit.

- * ----------	-------		------------------------------------------------

- * 01/15/2008	1.3			Bug is Fixed in the pppinit() fuction.

- *							: do not clear interrupt value, so fixed.

- *

- *		                   			Modification of ISR

- *                   				: Do not exit ISR, if there is interrupt.

- * ----------	-------		------------------------------------------------

- * 03/21/2008	1.4			Modification of SetMR() function

- *                   				: Use IINCHIP_WRITE() function in Direct or SPI mode.
